- the smart cards are purchased from a pay television vendor.
- the vendor typically activates the cards by passing them through an activating machine (not shown) which applies an activation algorithm.
- the cards remain active until certain predetermined criteria occur which turn the cards invalid.
- purchasing a smart card is associated with a subscription to pay TV services.
- the subscriber purchases more than one smart card he typically pays less for a second subscription than for a first subscription.
- a smart card is not uniquely associated with a specific decoder. Therefore, a valid smart card may activate any decoder of the type to which it fits. In such a case, there is a possibility that a subscriber may purchase several smart cards at a reduced price and sell them, at a price which is higher than the reduced price but still less than the full price, to other people.
- the system and method ofthe present invention may be employed to prevent such cases.
- a first smart card and a second smart card which are active may be deactivated in accordance with predetermined criteria.
- the predetermined criteria may include a predetermined date and/or a predetermined time.
- other criteria may be employed, such as number of purchases of premium programs or amount of money spent on purchases.
- the first smart card may include a predetermined first deactivation date and the second smart card may include a predetermined second deactivation date.
- Each of the deactivation dates may be stored in a memory zone in the corresponding smart card by passing the smart cards through a machine (not shown), such as the activating machine mentioned with reference to Fig. 1.
- the machine typically controlled by an algorithm in software, preferably burns data related to the deactivation dates into corresponding memory zones in the first and second smart cards.
- the memories of the first and second smart cards may be of the EEPROM (Electronic Erasable
- the above mentioned deactivation dates may be communicated to the first smart card and to the second smart card via the pay television network.
- the deactivation dates are maintained in terms of months or days.
- the first deactivation date and the second deactivation date may be different, and may be determined at time of purchase or at time of manufacture.
- television programs are decoded in a first decoder and in a second decoder to which the first and second smart cards are respectively coupled until the earliest ofthe above mentioned deactivation dates elapses.
- the second smart card is the first to be deactivated.
- Deactivation of the second smart card preferably occurs when a current system date matches or exceeds the second deactivation date. The match may be found by comparison of the current system date to the deactivation date stored in the second smart card. Such comparison is typically performed in a processor which forms part of the second smart card as mentioned herein above with reference to Fig. 1.
- the processor which forms part ofthe second smart card may compare the current system date with a deactivation date which is received via the pay television network.
- the second smart card preferably generates a message which is displayed on a TV to which the second decoder is coupled.
- the message typically indicates that the second smart card is deactivated, and programming material is not decoded. It is to be appreciated that the first smart card remains active and programming material is decoded at the first decoder.
- a subscriber preferably removes the first smart card from a first slot in a first card reader in the first decoder and replaces it by the second smart card.
- the first smart card is operative, when inserted in the first slot, to transfer to the first decoder chaining data which is used to reactivate the second smart card, and the chaining data is transferred to the second smart card when the second smart card is inserted in the first slot.
- the first decoder may be programmed to include the data required for reactivation ofthe second smart card at entitlement time, which may be when the first decoder and the second decoder are purchased.
- the first decoder may include a plurality of smart card slots, and the second smart card may be inserted in an unfilled slot while the first smart card is inserted in the first slot, the chaining data being transferred from the first card to the second card via the decoder.
- the chaining data may include a signature, a key or a seed which may be employed to at least one of validate, identify, verify and authenticate the second smart card.
- the chaining data also includes a digital representation of a time increment which may be employed to calculate a deactivation date.
- the time increment is typically specified in months and days.
- the signature is checked and compared for validity in a decoder processor which forms part of the first decoder, such as decoder processor 26 of Fig. 1.
- the processor which forms part of the second smart card may be operative to check validity ofthe signature received from the first decoder.
- the decoder processor of the first decoder adds the time increment to the current system date to generate a new deactivation date.
- the new deactivation date is stored in another memory zone in the second smart card.
- the new deactivation date is communicated, via the pay television network, to a pay television headend (not shown), which may later use the new deactivation date to deactivate the second smart card when the new deactivation date elapses.
- a processor which forms part of the first smart card rather than the decoder processor of the first decoder, may be operative to calculate the new deactivation date of the second smart card.
- the processor which forms part ofthe first smart card and the processor which forms part of the second smart card may communicate, via the first card reader, with a decoder memory which forms part of the first decoder, such as decoder memory 28 of Fig. 1.
- the decoder memory is preferably operable: to receive from the processor which forms part ofthe first smart card, and to store data including the new deactivation date of the second smart card, and one of a signature, a key and a seed identifying the first smart card; to provide the one of a signature, a key and a seed identifying the first smart card to the second smart card, when the second smart card is inserted in the first slot in the first decoder, in response to a first instruction transmitted by the second smart card; and to provide the new deactivation date to the second smart card in response to a second instruction transmitted by the second smart card.
- the second smart card transmits the second instruction to the decoder memory only if the signatures ofthe first smart card and the second smart card coincide.
- the new deactivation date which is received from the decoder memory is stored in the second smart card.
- the new deactivation date is calculated in a headend processor which is located at the headend ofthe pay television system, and the headend rather than the first smart card provides the new deactivation date to the decoder memory.
- the decoder processor of the first decoder After the new deactivation date is stored in the second smart card, the decoder processor of the first decoder provides the second smart card an instruction which reactivates the second smart card. Alternatively, the decoder processor of the first decoder informs the headend that a new deactivation date is stored in the second smart card, and the headend transmits an instruction which reactivates the second smart card. After the second smart card is reactivated, it may be removed from the first slot in the first decoder and inserted in the second decoder. Since the second smart card is reactivated, the pay television programs are decoded.
- Such algorithms may include adding multiple time increments to the current system date, and adding a constant number of hours to the time increment to achieve deactivation at any selected time of a day.
- time increment may be modified by the decoder processor of the first decoder or programmed by the manufacturer or the pay television vendor.
- variable time increments may be stored in the decoder memory which may be controlled by the decoder processor ofthe first decoder.
- first and second smart cards are preferably linked together at entitlement time and thus the first smart card recognizes the signature ofthe second smart card and vice versa. If the chaining data is provided by a decoder rather than by a smart card, then the first and second decoders are preferably linked together at entitlement time, and the first and second smart cards receive the chaining data from the first and second decoders respectively when inserted in the respective decoders for the first time.
- the new deactivation date may be later than the deactivation date of the first smart card.
- the second smart card may reactivate the first smart card.
- each card may reactivate any number of cards which are linked thereto. It is to be appreciated that reactivation of a card may take less than a second, or a few seconds if communication with the headend is required as described herein above.
- the two cards i.e. the first smart card and the second smart card
- the chaining procedure may initiate with the deactivation of the first smart card rather than the deactivation ofthe second smart card.
- the first decoder and the second decoder are also interchangeable.
- the first smart card may reactivate the second smart card twice, three times, or more before the first smart card is reactivated.
- the time increment may be calculated so that no two chained cards deactivate at the same time. If such a principle is maintained, an active card in the chained cards may always reactivate a deactivated chained card.
- the above mentioned chaining procedure gives the subscriber a very strong incentive to maintain both the first and second smart cards, and all cards chained to the first and second smart cards which he purchases from the vendor, in his residence in order to physically chain the cards at particular time periods. This makes it difficult, if not impossible, for the subscriber to sell one or more ofthe cards to another person.
- the first and second smart cards may be also employed to control access to a VCR (Video Cassette
- the subscriber may postpone deactivation of a card whose deactivation date has elapsed for a period of a few hours by, for example, pressing a key (not shown) in a remote control (not shown) to prevent deactivation while he views a selected program.
- the decoder processor of the first decoder or the processor which forms part ofthe second smart card, may add a constant time increment, such as an hour, to the elapsed second deactivation date.
- deactivation dates may be specified in hours, as well as in months and days, and deactivation may be selected to occur late at night or at other times of day at which television programs are not typically viewed.
- the chaining data for reactivation of a card is not transferred before a deactivation time elapses.
- a deactivation time elapses.
